When developing in Swift, you will eventually need to interact with Objective-C APIs. Most of the time this is fine, and fairly straightforward to do using #selector. However, every once in a while you will need to invoke an Objective-C selector that you did not write (usually when the selector is part of the iOS or macOS SDK), does not have a unique signature, or is just pretty hard to figure out. This article put out by Big Nerd Ranch’s Mark Dalrymple is an excellent rundown of how to properly invoke Objective-C selectors from Swift. He even covers really hairy signatures that may be very difficult to come up with on your own at first glance. Big Nerd Ranch —[…]

The latest iOS Dev Break episode was released on September 13, 2017, but a new episode is coming soon! iOS Dev Break Episode 13: 2017 September Apple Event iOS Dev Break 013: Thoughts and comments for iOS developers about today’s Apple Event and launch of the iPhone X! IDB013: 2017 September Apple Event

Yes. I’m a latecomer to the Sierra game (due mainly to an audio hardware driver I had to wait on to be upgraded to Sierra, which finally was updated but probably won’t be updated to High Sierra…), and most developers have probably already run into this problem and have dealt with it accordingly. However, I thought it might be a good idea to capture this here for posterity… Just this morning, immediately after upgrading to macOS Sierra, I experienced a problem by which Git began incessantly asking for my passphrase. This was an unwelcome surprise to me, but thankfully there’s a reasonably simple fix, thanks to this SuperUser suggestion: macOS keeps asking my ssh passphrase since I updated to Sierra – Super[…]

The latest episode of iOS Dev Break has arrived! This one was recorded just before WWDC, and a new episode will be published shortly! It Was A Very Googly Experience – IDB009 | iOS Dev Break In this episode: The return of iOS Dev Break! Adventures with the Google Play Store, Swift 4 and the Codeable protocol, plus AirPods and their amazing user experience!

I have been wanting the ability to merge two window’s collections of tabs in Google Chrome for some time now, because moving one tab a time from one window to another is tedious at best. I thought I’d need an extension for it, but it turns out that you can already do it in Chrome without any extra extension! I found this tip on the Google Chrome Product Forums, which tells how to do it: Merge two windows with multiple tabs Left-click the first tab in the window you want to merge. While holding the shift key, left-click the right most tab. All of tabs for the current window are now selected, so you can drag and drop them as as[…]

Somehow I don’t think I broadcasted this when it was available so now seems a good a time as any… My Core Bluetooth talk from Forward Swift 2016, “How Hot Is My Coffee? Sensors, Core Bluetooth and Swift!” has been up since last year, but thankfully it’s still up! Evan K. Stone: How Hot Is My Coffee? Sensors, Core Bluetooth and Swift! – Forward Swift 2016 Fitbit, Withings, Nest. The Internet of Things (IoT) innovation tidal wave has just begun, and those are just three of the more well-known players in the IoT and connected gadget landscape. It’s critical that iOS developers know how to connect and interact with BLE prototyping devices using the Core Bluetooth Framework provided by the[…]

Here’s the video for the talk on React Native I did for Forward Swift in March of 2017 in San Francisco! I’m very glad I didn’t have to wait until November for this one – the Forward Swift team has done an amazing job of getting out their videos in record time! Evan K. Stone: What’s This React Native Thing I Keep Hearing About? In our daily lives as iOS developers, we can usually happily keep coding away in Swift and ignore what’s going on in other software development communities, like that of JavaScript. However, there may be some advantages to at least becoming familiar with what’s going on in the world of React Native, and in this session you[…]

Evidently this got posted to Realm’s website back in November, and I was not informed. Better late than never! Evan K. Stone – Saving Lives with iBeacons You’ve probably heard of iBeacons, but have you seen them up close or developed apps for them? iBeacon technology is a fun and easy way to start working with Bluetooth Low Energy devices. Cloud City Development has been working with Pop Up Labs at MIT to help develop a solution for educating health professionals about the Maker Movement and how it positively affects the medical community. With the help of iBeacons, health professionals have learned how to start creating their own devices and tools! In this talk from AltConf 2016, Evan will introduce[…]

React Navigation for React Native is “collaboration between people from Facebook, Exponent and the React community at large” as this comment on the project’s GitHub page indicates: React Navigation is born from the React Native community’s need for an extensible yet easy-to-use navigation solution. It replaces and improves upon several navigation libraries in the ecosystem, including Ex-Navigation, React Native’s Navigator and NavigationExperimental components. React Navigation can also be used across React and React Native projects allowing for a higher degree of shared code. Once stable, NavigationExperimental will be deprecated in favor of React Navigation. React Navigation is a collaboration between people from Facebook, Exponent and the React community at large. Also interesting is the revealing that React Native’s NavigationExperimental will[…]

This was really bugging me because I don’t care for the Heart button Love/Dislike function in the latest versions of the Music app. Therefore, to bring back the star rating in iOS 10 Music app, you can do the following: Open the iOS Settings app from your Home Screen Find the settings for the Music and open it. About the fourth item down is the “Show Star Ratings” switch. Switch it on. When you enable the star ratings, you will find a new “Rate Song…” item when you tap on the song’s ellipsis button in the detail view of a playing song, with which you can rate the song with stars instead of Love/Disliking it. Based on information found at[…]
